k-on!:K-On! (けいおん! Keion!) is a Japanese four-panel comic strip manga written and illustrated by Kakifly. The manga started serialization in Houbunsha's seinen manga magazine Manga Time Kirara since the May 2007 issue, and also started a bimonthly serialization in Houbunsha's magazine Manga Time Kirara Carat since the October 2008 issue. A thirteen-episode anime adaptation produced by Kyoto Animation aired in Japan between April and June 2009. An additional original video animation episode was released in January 2010. A second season will begin airing in Japan in April 2010. The title of the series comes from the Japanese word for light music, keiongaku (軽音楽?), but in the Japanese context is similar to pop music.

K-On!'s story revolves around four Japanese high school girls who join their school's light music club to try to save it from being abolished. However, they are the only members of the club, and at first Yui Hirasawa, the main character, has no experience playing musical instruments or reading sheet music. Eventually, she learns how to be an excellent guitar player. The rest of the club helps her to buy a guitar, and they perform successfully at the school festival. kyoto animation:http://www.kyotoanimation.co.jp/akiyama mio:Mio Akiyama (秋山 澪 Akiyama Mio)Mio is a shy girl who is in the light music club and plays a left-handed, 3-Color Sunburst Fender Jazz Bass, with a tortoiseshell pickguard. She originally intended to join the literary club, but is forced into the light music club by her childhood friend and the club's president/drummer, Ritsu. She gets excellent grades in school, but is bad with listening to stories involving macabre experiences, and cowers whenever something gross is brought up. While she can be mature and strict sometimes, she gets embarrassed easily, and is often subject to teasing from Ritsu and Sawako, their club adviser. She cites that she chose bass since it is not the center of attention in the band, unlike the guitarist. Mio is more technical when it comes to music, and Yui often comes to her when she is in need of more guitar tutorials. She is the band's backing vocalist and takes over lead vocals whenever Yui is incapable of singing or forgets the lyrics. She writes most of the songs, although they usually feature some odd and overly girlish lyrics like "Light and Fluffy Time". As she is left-handed, she becomes entranced whenever she sees left-handed instruments. Due to an unexpected accident in one of their live performances (and partly due to her attractive appearances), she acquired a huge amount of popularity, and even a fan club for her is formed (much to her dismay considering the circumstances surrounding it), whose founding member is the former student council president, who also stalks Mio. Due to this, most of her classmates voted her to play as Romeo in their class play. Mio is seemingly a fan of Lomography, as she is often seen with a camera strongly resembling the Lomo LC-A during her summer training.
